Modelica library for simulating energy consumption of auxiliary units in heavy vehicles
Niklas Holländer Pettersson, Karl Henrik Johansson · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2003
Models that can be used to analyse the fuel consumption of auxiliary units in heavy vehicles are presented. With the purpose of evaluating the influence from various drive concepts and control principals, a model library is developed in the modelling language Modelica. The library contains a mixture of models developed from physical principles and models fitted to collected data. Modelling of the cooling system is described in some detail. Simulation results are compared with measurement data from tests in a wind tunnel.
